Where do I find the Class of Service Fare Basis Code?
 

I have booked tickets and used miles to upgrade, so therefore on the receipt it does not show the fare class, only First Class in R. I want to keep track of my mile Safari points and predict where I will be and if I have to do other things to get to the next level. Anyone have any insight as to where I would look? I went to my itineraries, trip summary and receipts and can't find any info. TTU was no help at all.

I take it that you opted for the upsell at the end of the reservation process where it says for 30K miles upgrade to First? As such, when they sent you a receipt it probably just lists the booking class as R. I think your best bet is to call the airline, unless someone else has some insight into this problem.

Thanks for your reply. I guess I'll have to call them.
